About UsJMT provides bridge inspections and other types of
structural inspections for federal, state, county, agency,
and privately-owned bridges and structures, consistent
with National Bridge Inspection Standards (NBIS). These
range from routine, biennial inventory inspections to in-depth,
emergency inspections, including underwater inspections.

Types of StructuresHighway & Railroad Bridges:• Simple and continuous steel I-beams, box beams, trusses, and girders,
including curved girders
• Reinforced concrete beams and slabs, including voided slabs
and T-beams
• Simple and continuous prestressed concrete beams and slabs, including
AASHTO I-beams, box beams, voided slabs, bulb tees, and segmental box
• Reinforced concrete box culverts and arches
• Stone and masonry arches
• Complex and moveable bridges, including electrical/mechanical systems
• Timber bridges, bulkheads, and piles
• Steel pipe culverts and arches
Other Structural Types:• Ancillary structures, including overhead and cantilever signs,
high mast light poles, and traffic signal poles
• Dam and gate structures
• Retaining walls
• Noise walls
• Bulkheads and other marine structures

Bridge Inspection
InspectionsAll inspection work is performed under the direction of registered professional engineers. JMT
team leaders have completed the NHI Safety Inspection of In-Service Bridges course as
well as other specialty training, and conduct the following types of inspections:
• Routine biennial
• Fracture critical member inspection
• Confined space inspection
• Interim inspection
• Emergency inspection
• Scour inspection and evaluation
• Underwater inspection
• InspectTech data input
We use the latest technology and equipment to optimize the efficiency,
quality, and cost- effectiveness of our field crews and office tasks.
Specialized access equipment and rigging allow access to areas
of bridges that normally require traffic lane closures, thereby
minimizing disruption to the traveling public.
JMT has performed bridge inspection services for on-call
and scoped projects at numerous locations throughout
the United States. We can mobilize an inspection team
within a few hours for an emergency response.
Emergency/Priority Repair Design
JMT has the extensive emergency and priority repair design experience necessary to
develop cost-effective repairs for problems identified during inspection or resulting
from collision damage, fire damage, and natural disasters.
We provide 24/7 inspection and design services to meet the client’s needs in
an emergency, including construction supervision of the repair work.
Our engineers quickly respond to emergency situations to assess
initial damage, provide recommendations related to public safety,
and complete the required design services rapidly. JMT develops
cost-effective solutions, minimizes inconvenience, and
eliminates safety hazards posed to the traveling public.
Structural Analysis & Load RatingsJMT has extensive bridge load ratings and structural analysis experience.
We utilize a variety of load rating programs to perform 2D and 3D finite
element modeling in accordance with AASHTO and client requirements.
We have rated thousands of bridges, from simply supported structures
to complex structures and moveable bridges using LRFD, LFD, and ASD
methodologies.
Testing & SamplingJMT employs a wide range of non-destructive and destructive testing
techniques. Our capabilities include dye penetrant, magnetic-particle,
ultrasonic, radiographic, electronic thickness measurement instrument,
rotary hammer, chain drag, chloride ion, concrete compressive cores,
coupon sampling, and paint sampling.
